why is my stomach grumbling and making bubbly noises?

Question

I am hungry. thats why right?
but why does it happen?

Answer 1

OK well I asked this question too and I never saw any answers that answered it enough for me. So I researched it myself.

When our stomach is really hungry, it contracts and squeezes air around. That much everybody seems to know, but I wanted more details. The stomach is kind of like a long curved sack. From what I can tell, when a stomach is digesting food, it pinches itself in the middle and the contraction moves downward, mashing and compacting the half-digested food toward the bottom of the stomach (the part near the intestines). The pressure gets strong when this happens, and most of the food gets squirted back up through the contraction into the upper part of the stomach. This is how the stomach mixes and churns food thoroughly.

We don't usually feel these motions, even though they can be kind of strong, because when the stomach has food in it, it fits kind of snugly in its space -- just under and behind the bottom of the left ribcage. So when it is grinding food, it can only twist and kink so much, since it has food in it to "cushion" everything.

When we are hungry, our stomachs go through a kind of phase of super-activity that lasts about ten minutes (this is when it really GROWLS hard -- you notice it usually only growls like three or four or five times, then just stops and hunger subsides). But since there's no food in there, when the stomach pinches up and squeezes air downward inside of itself, it also twists and kinks up more, which pulls at all the "ligaments" (cords and membranes) that connect it to the surrounding organs. This is how and why we feel that slow knotting up or puckering feeling as our stomach gets ready to growl. Then, when the pocket of air is compressed too much, it is forced upward through the tight ring of contraction, so that the stomach, which is already bunched up like a row of fists, vibrates and that noise is made.

It's a pretty crazy sensation anyway, annoying as well as embarrassing when it's loud and people around you are quiet. Thankfully it will only growl a few times in a row, then stop for an hour or two (according to what scientists and doctors say, but I find this is true for me also...I start getting hungry for like a half hour, then my stomach has a growling tantrum, then it stops and I'm not really that hungry any more).

Leaning over or crossing or pressing my arms into my stomach, plus taking deep breaths and holding them, and tightening my stomach muscles all work SOMETIMES to make a hunger pang pass by without growling. But only sometimes...

because your appendix is rubbing your stomach and your walls of your stomach are rubbing to each other. If your stomach doesn't have food, then it will keep rubbing to each other until it hurts. If you have food in it, it'll rub the food to digest it. Your food is like the shield to prevent the rubbing.

because it is filled with parasites
